Fix bool type appearing in GDExtension header

[Bromeon]

Repetition of the exercise in #71696 and #81247.

Since 3 is a good number of times to start automating, I'll look into preventing this.

Eep, sorry! This could be helped by the idea for generating the header from JSON/XML, because we could have a list of allowed types. I'm going to try to explore that in the 4.4 dev cycle if I find the time, although, it's not super high priority.

Anyway, this change looks good! Thanks!

Just running the header through a C compiler already catches most of these issues, which is what I did in #96408. Would be nice to have some validation like this soon, because incorrect headers keep breaking downstream projects 😉
